Well, the only endocrine organ found in the roof of the Third Ventricle is the PINEAL GLAND.
The Third Ventricle is a passageway of Cerebrospinal Fluid from outside of the brain to the inside. It is located on the posterior (back) portion of the brain.

How does the density of most substances change when they are heated?
generally, the density of a substance decreaces when heated, with the exception of ice, which is less dense than water.
When most substances are heated they....?
They expand
How will the density change if the temperature increased to 125?
The density of most substances will change if temperature is increased. The amount of change depends on the difference between the two temperatures.
How are temperature and density of air related?
cold air has higher density, by hot air is opposite
What happens to most substances when they are heated?
They expand due to the molecules speeding up.

What expands when it is heated?
Most substances expand when heated.
What expands when its heated?
Most substances expand when heated.
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
When the temperature of a substance decreases significantly most substances will contract.
When most substances are heated they....?
They expand
How will the density change if the temperature increased to 125?
The density of most substances will change if temperature is increased. The amount of change depends on the difference between the two temperatures.
Why temperature increases dencity decreases?
Density is mass divided by volume. For most substances, when the temperature increases the volume will increase (assuming constant pressure), but the mass will of course remain unaffected.
What do most substances like the liquid in a thermometer do when they are heated?
expand
What happens when most substances are heated?
All get very hot.
When a substance is heated what happens to its mass volume and density?
The mass remains unchanged. In most case the volume increaes so that the density decreases. An exception, very important for aquatic life, is that water behaves in an anomalous way just below 4 deg C.
Does density of a substance generally decrease while the temperature increases?
No, the density of most substances typically decreases as the temperature increases. This is because the increase in temperature generally leads to an increase in the average kinetic energy of the substance's particles, causing them to move faster and occupy a larger volume. As a result, the density, which is defined as mass divided by volume, decreases. However, there are some exceptions, such as water, where the density increases between 0°C and 4°C due to changes in the structure of the water molecules.
What happens to a solid when is heated?
A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
